It’s frustrating when you’re vacuum packaging meat or fish for storage, only to have a piece of bone puncture the bag, forcing you to start over. Solution: Just place a sheet of Bone Guard over the bone or any sharp edge to prevent puntures and leaks. The heavy-duty 6-ml.-thick material provides the ultimate in bag protection. Each sheet is 4.5" x 5" in size and clear for full product visibility. Bone Guard works with all suction and chamber-type bags and vacuum packaging machines. 150 sheets per box.
